New Pool filled Jan 2008.
I thought I had my new pool under contol the past 6 months but we had a major change in my calcium lelevs increasing from 250ppm for the past 6 months to 450ppm in the past week.
The only thing that happened was a rain that added about 1" of water in the pool and I added one packet of Leslie's shockit with the orange strip call ChlorBrite.
The weird thiung is that any liquid test I do or the store we get 450 ppm. I use the strips it shows 250ppm. I just did a liquid test a few minutes ago and it was 450ppm and I made sure I mixed well between drops and still came up with 450ppm. Stuck in a fresh strip and it showed 250 PPM.
I plan on taking my water to 2 differnt pool stores today to see what they come up with.
